Common print materials

So if you an just getting interested in 3D printing, or are already involved in 3D printing, stop by Freeside this Thursday night at 7:30pm. People already familiar with open source 3D printing are also encouraged to come and help teach or just meet fellow enthusiasts.

One of the costs of running an inkjet based 3D printer is that the cartridges have to be replaced on a regular basis. The Z400 and Z402 use Canon BC-20 ink cartridges which are readily available.

There are currently two known ways of making these cartridges ready for the printer.

The first method is to cut the cartridge in half, remove the foam inside, cut a Blue Falcon BD-50 Centrifuge tube in half, and epoxy it and a small O ring to the reservoir at the bottom of the cartridge. This is how the cartridges that are sold by Z Corp are made.

An alternative method is two drill two holes in the cartridge, epoxy down some type of barb, and flush the cartridge. This is the method I am currently using in my Z402. Click below for full instructions and a few pictures of the process.
